[   ]
Description The type of supply and the needful equipment is depending upon the numbers of samples and the consumption of liquid nitrogen. The consumption of liquid nitrogen again is evaluated by the storage capacity and substantially by the numbers of access and freezing processes. In order to ensure an economic nitrogen supply, the pressure inside the storage tank should be kept constant at 1.5 bar. Out of this derives a boiling temperature of -187 °C and physically conditioned relieving losses of 9.3 %. Working with the normal storage pressure at 6 bar causes a boiling temperature of -175 °C and the relieving losses increases up to 23 %.
